When consumed in large quantities, these fats can cause vomiting, diarrhea, and sometimes pancreatitis in dogs. Additionally, macadamia nuts have their own unique, negative effects on dogs. When ingested, they can cause weakness, hyperthermia, vomiting, tremors, and other bad symptoms, which typically last 12 - 48 hours.
